RDK-737

1.44W non-isolated buck converter for 12V, 120mA power supply using 900V LinkSwitch-TN2 LNK3294G/P. In metering applications this is used to supply the control circuits and micro controller. The highly integrated solution offers lowest possible component count and integrates a 900V MOSFET and control circuitry into a single low cost IC. Regulation is achieved using a low cost resistor divider feedback network. The switching frequency jitter feature of the LinkSwitch-TN2 family and the 66 kHz switching frequency of operation helps reduce EMI.

• 85VAC to 440VAC input, 12V/120mA output
• Suitable for small appliance / metering application
• 900V maximum drain voltage
• Highly integrated solution
• Lowest possible component count
• No optocoupler required for regulation
• Thermal overload protection with automatic recovery
• <lt/>30mW no-load consumption, <gt/>73% efficiency at full load
• <lt/>±5% load regulation
